1. Considerable information is carried by the linear sequence of amino acids in proteins. Which of the following best describe the nature of that information. (FILL IN TWO BUBBLES)a) It dictates the three-dimensional folding and catalytic ability of a proteinb) It can be transmitted from one generation to the next.c) This information ultimately dictates the metabolic ability of a cell.d) Using this information requires a complex translation process.e) Expression of this information requires an input of energy.

2. Energy is released when a match ignites aviation fuel. Which of the following make this a reasonable analogy to describe how life generates energy? (FILL IN TWO BUBBLES)a) Both fuel ignition and life are processes that involve redox chemistry.b) Aviation fuel is derived from biological material deposited under ground as oil.c) Aviation fuel is reasonably stable until it contacts the match - resembling foodthat is reasonably stable until catalyzed reactions release its energyd) The loud noise and gas release resemble human digestion.e) Aviation fuel can serve as fuel for almost all living things
